What is the type of elements of the jagged array in C#?

CsharpProgrammingServer Side Programming

A jagged array is an array of arrays, and therefore its elements are reference types and are initialized to null.

Let us see how to work with Jagged array −

Declare a jagged array −

int [][] marks;

Now, let us initialize it, wherein marks is an arrays of 5 integers −

int[][] marks = new int[][]{new int[]{ 40,57 },new int[]{ 34,55 }, new int[]{ 23,44 },new int[]{ 56, 78 }, new int[]{ 66, 79 } };

Let us now see the complete example of jagged arrays in C# and learn how to implement it −

Example

 Live Demo

using System;

namespace MyApplication {
   class MyDemoClass {
      static void Main(string[] args) {
         int i, j;
         int[][] marks = new int[][] {
            new int[] {
               90,
               95
            }, new int[] {
               89,
               94
            }, new int[] {
               78,
               87
            }, new int[] {
               76,
               68
            }, new int[] {
               98,
               91
            }
         };

         for (i = 0; i < 5; i++) {
            for (j = 0; j < 2; j++) {
               Console.WriteLine("marks[{0}][{1}] = {2}", i, j, marks[i][j]);
            }
         }
         Console.ReadKey();
      }
   }
}

Output

marks[0][0] = 90
marks[0][1] = 95
marks[1][0] = 89
marks[1][1] = 94
marks[2][0] = 78
marks[2][1] = 87
marks[3][0] = 76
marks[3][1] = 68
marks[4][0] = 98
marks[4][1] = 91
